Keep pace with your changing attack surface
Engineering moves fast. Security needs to keep up. Always-on attack surface monitoring spots exposed assets and tells you when things change.

Join 3,000+ companies securing their attack surface with Intruder





























































Uncover shadow IT
Intruder finds the things outside your inventory, like a subdomain a team forgot or a new cloud service, and pulls them in automatically.

Shrink your attack surface
Some of what's facing the internet was never meant to be there, like a database or an old admin panel. Most tools wave those through; Intruder flags them as the risk they are.

Catch new exposures fast
Your environment is constantly changing. Intruder detects these changes in real time and automatically scans new assets for vulnerabilities.

Keep eyes on your entire digital estate
Connect to your environment
Connect your AWS, Azure, Google Cloud, and Cloudflare accounts and add any domains and IPs. Your first scan launches immediately, and new cloud assets are picked up and scanned automatically as they're created.
Proactive scanning
Port scans run daily to track what's exposed. New service scans trigger when something in your environment changes, and emerging threat scans run when a major new vulnerability is disclosed.
Attack surface view
See every monitored port, the service running on it, and the version behind it, with a screenshot of each web service. Search or filter by port, service, product, host status, or certificate expiry to find what you need in seconds.

Attack surface management (ASM) is the continuous process of discovering, assessing, and reducing every digital asset an attacker can reach, including systems that are unknown or unmanaged. It goes beyond vulnerability scanning by flagging assets that shouldn't be internet-facing at all, not just assets with known CVEs.
Vulnerability management finds known weaknesses in your systems. Attack surface management starts a step earlier, finding the systems themselves, including ones you didn't know were exposed, and flagging exposures that have no CVE but still create risk, like an open database or a forgotten admin panel. Intruder does both in a single platform. Read more about ASM vs VM.
Every monitored port, the service running on it, and the version behind it, with a screenshot of each web service. You can search or filter by port, service, product, host status, or certificate expiry. It gives you a live picture of what's exposed and what's changed.
